Questions and answers about the product.

You should only use the original Lightweight brake pads included as standard original equipment. We have worked in cooperation with our technical partner to develop and design our brake pads specifically for our carbon-fibre system. If you use brake pads other than our original Lightweight brake pads, they may seriously damage the brake track areas or leave virtually invisible residues that may cause brake problems or loss of control. You can purchase the brake pads from a dealer or directly from Carbonsports GmbH.

If you use different brake pads you will lose all rights to make claims under warranty, goodwill and/or WHEELPROTECTION.

We recommend the use of tubeless sealant. We use the tubeless sealant from the firm No Tubes. The benefits lie not only in that if one rides over sharp objects one does not necessarily get a flat tyre and one can save having to put on a new tyre or replacing the tube, one can also avoid damaging the carbon rim flanges as it does not lead to a “roll-out” following a rapid loss of air in the tyres. This is to be particularly recommended for the “Standard C“ models as well, as a damaged rim flange is irreparable. Moreover, a flat tyre can result in a rapid loss of control of the bicycle which could lead to a serious fall.

The tubeless sealant is best poured in prior to putting on the tyres. To avoid the valve clogging, it should be removed before filling. In addition, one can treat the valve rubber lightly with Vaseline for example. If in use in association with disc wheels note should be taken that it is almost impossible to subsequently fill the tyre with tubeless sealant.

Our models Meilenstein Tubular and Gipfelsturm are approved for the cyclocross in terms of the geometric stress alone. Are limitations in terms of durability of the braking surface is considerably compared to the pure road use. Thus, the braking surface of our cyclocross wheels in the use of wear out much faster. Information about the shelf life can not be made ​​at this point, this is very much on the driver, route and depending on how dtyir.

For registered Lightweight products, CarbonSports offers crash replacement and goodwill provisions – including for material defects (warranty) beyond the statuary liability period. In respect of irreparable damage, e.g. as a result of an accident, we guarantee a reduction of 30% on the respective list price when buying a new Lightweight product as a replacement. The right of replacement must be claimed direct from CarbonSports GmbH. When this provision is exercised the irreparable Lightweight product will remain in our possession.

Slight damage to your Lightweight products will also be repaired by us for free, even after the expiry of the statutory warranty period – the maximum time spent on repairs is 0.5 hours. We alone will decide whether a repair will be carried out for free – in no case is there a right to free repair of damage caused by the customer! In cases of damage caused by the customer, please send us the affected Lightweight product for assessment. After estimating the time required for the necessary repairs, these will either be carried out for free or you will receive a quotation from us. The decision as to whether the repairs are to be carried out will be yours alone.

You will also find this and further information in the user manual and on our website at www.lightweight.info. Please register your Lightweight wheels within 8 weeks after receipt!

Each Lightweight wheel has a laminated magnet (on the Ventoux model the magnet is fixed to a spoke), approximately opposite the valve. If the construction method of your racing bike fork does not allow for the correct orientation of the front wheel sensor on the laminated magnet, inquire in the specialist trade about a suitable wheel magnet! Never use a wheel magnet with a screw clamp – the clamping screw seriously damages the fibres of the carbon spokes. A serious accident could be the result.

As well as the application instructions of the manufacturer of the tyre glue and/or the adhesive tape, you should also make sure that you do not use tubular tyres that are too wide. In respect of tyres that are too wide, the tyre cross-section and the rim bed no longer match optimally, such that the adhesive force of the glue/adhesive tape can be diminished.

Preferably you should choose wheels with a width of 22–24 mm, the maximum permissible tyre width is 27 mm.

CarbonSports makes no special limitations or approvals for the use of tyre adhesives.

However, we recommend the use of tyre adhesives from Continental – they have an excellent record with respect adhesive power and durability, with both the standard adhesive and the special adhesive for carbon rims.

Basically we recommend the use of tyre adhesive for fitting tubular tyres. This provides the most durable connection between tyres and rims.

However, we have also had first class experience with the adhesive tape “Extrem“ from TUFO; but please note that TUFO gives no warranty in connection with other tyre manufacturers – this applies only to use with TUFO tyres.

Basically there are two different types of valve extensions, both of which can be used.

- extensions that are screwed onto the complete valve and which can be removed again after pumping. In this variant the valve is hidden in the valve passage and can no longer be closed
- fixed extensions which are inserted between the valve core and the valve shaft of the tube. These stay there; the valve is thereby always accessible and can be closed.

Because of easier handling, we recommend the second variant. Optimised for use with the Continental tubular tyres and/or tubes in association with the Lightweight high-profile wheels, we offer a light aluminium valve extension weighing only 1.6 grams, which you can buy from your specialist retailer.

No. Lightweight wheels may not be used on tandems. The lateral forces arising caused by a turning manoeuvre or acceleration, are under certain circumstances too great and could lead to a wheel collapse. Lightweight wheels are designed exclusively

- for fitting on standard racing and time-trial bikes.
- see the user manual, technical data, for the respectively permitted functional range.

With the use of Lightweight wheels you lose all warranty and WHEELPROTECTION rights.

Sand and dirt on the brake track area and in the brake pads have a negative influence on service life. When you brake, this film of dirt acts like sandpaper and destroys the surfaces. So be sure to clean your wheels and brake pads regularly, especially when you have been cycling in the rain.

Replace your brake pads once a year.

Check the brake track areas at regular intervals for residue from the brake pads. If there is residue from the brake pads on the rims, you will also hear a loud noise when you brake. Brake pad residue also generates increased heat build-up on the rims, which can lead to unpleasantly jerky braking.

For preference, you should clean off brake pad residue with our cleaner for brake track areas or with methylated spirits.

Also, make sure that your brake pads are adjusted correctly, in accordance with the instructions in our owner's manual.

Check the toothed lock washers of your freewheel system every 5000 km. For information on how to do this, see our technical documentation, which is enclosed with your wheels. Replace damaged components with original DT Swiss parts only.

Firstly, strong juddering when braking is very annoying and, secondly, can be dangerous as well, if your bicycle cannot be controlled properly when braking.

- Please check that the correct setting as well as the cleanliness of your brake pads as described in your user manual.
- Regularly clean the brake flanks of your Lightweight wheels with a plastic scraper, to remove brake pad residue. If necessary use a cloth soaked in a little petrol or spirit for the remaining residue.

Finally, test the brakes. Note that the braking response may have changed. If there is no improvement or the juddering is in a range unacceptable to you, send the wheel to our Service Department in Friedrichshafen, adhering to our repair terms and conditions.

Unfortunately, a complete break of one or more spokes is not repairable.

Individual breaks or fibre damage on the spokes are reparable, insofar as 2/3rds of the width of the spoke is not affected. In addition, it is necessary to check whether the spoke break has led to a loss of tension, which no longer permits a renewed centring of the wheel.

In respect of irreparable damage, you can claim our crash replacement, insofar as you have registered your wheel with us in due time. Should you have concluded a still valid WHEELPROTECTION for your Lightweight wheel, you can avail of this.

A complete break of the rim ring is irreparable. If the rim is only partially broken, we can repair it under certain circumstances.
